Pine Trees Produce Sap When Healing

Q. One of the pine trees in my backyard has developed a split in the bark and is oozing some sap. The trees were planted about 10 -12 years ago and are now 12 -14 "in diameter. Is this something we should be concerned about?

None of these pictures are from the reader but it is easy to see that pine trees, when they are injured, produce an abundance of sap.

A. If the trees appear otherwise healthy, most likely not. When pine trees have wounds, it is normal for them to “leak” sap. It is their way of healing from wounds.When you do see sap from pine trees it is an indication that there was damage done.
            Make sure the tree is getting enough water. Also, make sure it is not watered too often.Having adequate water speeds the recovery from wounds. The trees canopy is a quick way to know if your pine tree is receiving enough water. Dense canopies with lots of new growth is a good indicator enough water is being applied.
            Water these trees deeply but infrequently. In other words, give them big drinks of water and then hold off as long as you can before the next irrigation. Deep irrigations 2 or 3 times a week should be enough.
